''Urodynamics, 3rd edition'' takes into account the technological innovations and new techniques that have been introduced since the publication of the 2nd edition in 1997. A simple yet practical guide to the functional investigation of patients with incontinence and voiding disturbances, the text makes clear the fundamental and vital contribution of urodynamic investigation to the management of patients with lower urinary tract dysfunction. The new terminology from the International Continence Society has been introduced, references fully updated and standardization reports in the Appendix completely revised. Urodynamics is now widely accepted and most hospitals now recognise it as an essential part of the diagnostic process in urology and gynecology. Specialists in geriatrics, pediatrics and neurology also appreciate the importance of urodynamics in the investigation of a large number of their patients.
